Introduction: The detection of minerals using remote analytical techniques has the advantage of performing rapid chemical analysis of a variety of targets without sample collection. This saves significant time in planetary explorations using rovers and provides a large number of targets accessible to a lander near its landing site. The University of Hawaii (UH), in collaboration with Los Alamos...

We demonstrate the application of non-gated laser induced breakdown spectroscopy (LIBS) for characterization and classification of organic materials with similar chemical composition. While use of such a system introduces substantive continuum background in the spectral dataset, we show that appropriate treatment of the continuum and characteristic emission results in accurate discrimination of...

Lithium-ion batteries (LIBs) are promising energy storage devices for portable electronics, electric vehicles, and power-grid applications. It is highly desirable yet challenging to develop a simple and scalable method for constructions of sustainable materials for fast and safe LIBs. Herein, we exploit a novel and scalable route to synthesize ultrathin nanobelts of anatase TiO2, which is resou...

a r t i c l e i n f o This study shows a 23-fold improvement of the sensitivity in the determination of copper in soil samples when using Microwave-Assisted Laser-Induced Breakdown Spectroscopy (MA-LIBS) compared with our conventional LIBS. This comparison between MA-LIBS and LIBS was performed with identical ablation conditions and detection geometry. The signal enhancement obtained with MA-LI...

Abstract Positron Emission Tomography (PET) studies [1] of the evolution Simian Immunodeficiency Virus (SIV) (the monkey analogue Human (HIV) have revealed that SIV is localised in different organs at stages infection. Promising routes to completely eradicate HIV virus particles involve therapies target infection cellular level. Our previous μ -Particle Induced X-ray ( μ- PIXE) very large varia...

Both standoff Laser Induced Breakdown Spectroscopy (LIBS) and Raman technologies have recently made great strides towards being deployed for operational use. Both technologies have demonstrated impressive capabilities of detection and discrimination of residue amounts of explosives at distances of 50+ meters in recent tests at the National Training Center, Ft. Irwin, CA, and Yuma Proving Ground...

LIBS is traditionally an atomic emission spectroscopy involving sampling, atomization and excitation of a sample by laser ablation. The radiative cooling of the created plasma is spectrally analyzed to provide the elemental composition of a sample of interest. In 1962, two years after the invention of the laser, Jarrell Ash Co. developed the Laser Microprobe that revolutionized the elemental mi...

Arginine-glycine-aspartic acid (RGD)– mimetic platelet inhibitors act by occupying the RGD recognition site of IIb/ 3 integrin (GPIIb/IIIa), thereby preventing the activated integrin from reacting with fibrinogen. Thrombocytopenia is a wellknown side effect of treatment with this class of drugs and is caused by Abs, often naturally occurring, that recognize IIb/ 3 in a complex with the drug bei...

Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy which utilizes the emissions produced by a laser-produced plasma. A pulsed laser is focused onto a sample with enough energy to ablate the material and generate plasma. Light from the plasma is collected by an optical system and transported to a spectrometer for spectral analysis, which can yield elemental and...
